VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 629,293, dated July 18,1899.

Application filed November 21, 1898. Serial No. 697,003. (lilo model.)

To all whom, it may concern.-

Be it known that I, CHARLES WALTER HATHAWAY, a subject of the Queen ofGreat Britain, residing at Coventry, in the county of Warwick,F.ngland,haveinvented acertain new and useful Improvement in Velocipedes and theLike, of which the following is a specification.

My invention relates to velocipedes and the like having forkwcarriedwheels, and has for to reduce vibration arising from inequalities in orobstacles on the road or other surface on which the said veloeipede maybe traveling; and my invention consists, essentially, in making theblades or fork of a special form, hereinstraight, but are afterdescribed and illustrated, and particularly pointed out in the claim.

In the accompanying drawings, Figure I is a side elevation, and Fig. IIis a front elevation, of such a fork. Fig. III shows transverse sectionsof the blade ofthe fork at the respective points in Fig. II,respectively, connected therewith by the horizontal lines. Fig. 111 isdrawn'to a larger scale than Figs. I and II. I

Similar letters and numerals refer to similar parts throughout thedrawings.

The upper end 2 of each blade A is made of oval section, and the majoraxis is arranged parallel to the plane of the wheel to be carried, asusual, so as to meet the great foreand-aft strain falling on the upperend of the fork. The lower end 6 of the blade is also made of ovalsection; but here the major axis instead of being arranged parallel tothe plane of the wheel, as at present usual, is arranged at right anglesthereto. The sectional form gradually changes from the one oval to theother between the two ends of the blade, as

shown by the sections 3, l, and 5 in Fig. III,

passing through a circular sectional form at or near the point 4:. Theblades may be preferably curved, more or less, as shown. The sectionalcircumference is preferably gradually reduced from the upper end to thelower and in such a way that in front or rear elevation the same widthof blade is maintained from top to bottom, the major axis of thelowerend 6 of the blade equaling the minor axis of the upper end 2 thereof.The said width is preferably somewhat greater than now usuaLso as toincrease the lateral rigidity of the fork. In other respects the f0rkmay be constructed in any suitable manner.

From the above description the application of my invention to othersuitable velocipedes and the like having fork-carried wheelswill bereadily understood. A fork constructed in the manner above describedallows the wheel carried by it to yield in its own plane whenencounteringinequalities and obstacles much more readily than a fork ofthe usual form wherein the oval or D shape section of the blades havingthe major axis parallel to the wheel is maintained throughout. l l

-\Vhat I claim, and desire to secure by Letters Patent of the UnitedStates, is-

Avelocipede or like fork the upper ends of the blades of which are ofoval section having the major axes parallel to the plane of the wheel tobe carried, the lower ends of oval section having the major axes atright angles to the plane of the said wheel,'and the intermediate partsgradually changing from the one form to the other, substantially as andfor the purpose set forth.
